How to restrict window/form resize to the initial values set in FireFly Designer

[Jean-Pierre LEROY]

Hi Paul,

I saw in the forum two interesting threads that explain how to setup the min and max size values for a specific Window/form.

So to restrict window/form resize to specific values, I use this code :

Code Select Expand


Function FORM1_CUSTOM ( _
                      hWndForm      As Dword, _  ' handle of Form
                      wMsg          As Long,  _  ' type of message
                      wParam        As Dword, _  ' first message parameter
                      lParam        As Long   _  ' second message parameter
                      ) As Long

    Local MinMaxPtr As MINMAXINFO Ptr

    Select Case wMsg
        Case %WM_GETMINMAXINFO
            MinMaxPtr= lParam
           
            ' specify the minimum value for dialog resize
            @MinMaxPtr.ptMinTrackSize.x= 394
            @MinMaxPtr.ptMinTrackSize.y= 333
    End Select
   
End Function


It works without any problem; I have nevertheless three simple questions:

1. Do you plan to provide in FireFly3 a separate message handler for WM_GETMINMAXINFO instead of using the CUSTOM message handler ?
2. Do you plan to provide in FireFly3 in form properties the min and max size values for the height and width of a Window/Form?
3. Is-it possible to retrieve inside a FireFly project the initial height and width values that are set in the FireFly Designer for a specific Window/Form ?

Thanks

1. Do you plan to provide in FireFly3 a separate message handler for WM_GETMINMAXINFO instead of using the CUSTOM message handler ?

I did not plan to separate that message. I doubt that it is a popular message that needs to have its own handler (unlike a message like WM_SIZE for example).

2. Do you plan to provide in FireFly3 in form properties the min and max size values for the height and width of a Window/Form?

No - I did not. If there is enough demand for such properties then of course I will add it.

3. Is-it possible to retrieve inside a FireFly project the initial height and width values that are set in the FireFly Designer for a specific Window/Form ?

Sure. You would have to create two global long variables (or a global Rect variable) to hold the values and then retrieve the sizes in the WM_CREATE handler. Use GetWindowRect rather than GetClientRect when determining the sizes because GetWindowRect would take into account the borders sizes of the form.
